Malaysia vowed Saturday that it would not give up on trying to find the missing jetliner and announced details of a multinational investigation team to solve the aviation mystery, as the search for the plane entered its fifth week.

Military and civilian planes, ships with deep-sea searching equipment and a British nuclear submarine scoured a remote patch of the southern Indian Ocean off Australia’s west coast, in the increasingly urgent hunt for debris and the “black box” recorders that hold vital information about Malaysia Airlines Flight 370’s last hours.

After weeks of fruitless looking, officials face the daunting prospect that sound-emitting beacons in the flight and voice recorders will soon fall silent as their batteries die after sounding electronic “pings” for a month.

China’s official news agency, Xinhua, reported late Saturday that a Chinese ship that is part of the multinational search effort detected a “pulse” signal in southern Indian Ocean waters on Saturday. The report said it was not determined whether the signal was related to the missing jet.

The report said a black box detector deployed by the vessel, Haixun 01, picked up a signal at 37.5Hz per second at around 25 degrees south latitude and 101 degrees east longitude.
